In a large bowl, mix together the shortening and 1 1/2 cups of white sugar until smooth. Stir in the eggs one at a time, blending well after each. Combine the flour, baking soda, cream of tartar and salt; stir into the batter until blended.

Roll the dough into balls the size of small walnuts. Roll in a mixture of 2 tablespoons sugar and 2 teaspoons cinnamon. Place 2 inches apart on an ungreased cookie sheet.

Bake in the preheated oven for 8 to 10 minutes or until lightly browned, but still soft.
